Voluntary dehydration was examined in young unacclimatized men walking under simulated desert conditions. Thirty-three subjects (20-33 years) walked on a treadmill (4.82 km.h-1, 5% grade) for 30 min.h-1 for 6 h in a hot environment (40 degrees C db/26 degrees C wb, 4.02 km.h-1 windspeed). Cool (15 degrees C) water was provided ad libitum in canteens. Because thirst is stimulated and drinking sh...

The effects of exercise, water temperature, and food consumption on patterns of ad libitum drinking were studied in 33 men during 6 consecutive cycles of 30 min walking (4.8 km.h-1, 5% grade) and 30 min rest in a climatic chamber (40 degrees C, 40% relative humidity). On two nonconsecutive days, subjects consumed 15 degrees C (cool) water during one trial and 40 degrees C (warm) water during th...

Data on beverage consumption patterns in early life are limited. The aim of this study was to describe beverage consumption by sociodemographic characteristics, along with water intake and sources of water among U.S. children aged 0-24 months. Data from 2740 children in the 2005-2012 NHANES were analysed. Food intake was determined via one 24-h dietary recall. Beverages were categorised accordi...

The objective was to compare the effect of dairy and nondairy beverages when consumed with carbohydrate at breakfast on subjective appetite, food intake (FI), and postprandial glycemia (PPG) in healthy young adults. Twenty-six healthy males and females (13 males and 13 females; 23.0 ± 2.6 years; BMI: 22.3 ± 1.5 kg/m2) participated in a randomized crossover study. They consumed nonisocaloric amo...

Limited biological information about Phyllophaga ephilida , a major sweet potato pest in Louisiana, is available. In 2001 and 2002, a study was conducted in the laboratory to investigate the feeding preference of adult Phyllophaga ephilida (Say) (Coleoptera: Scarabaeidae) for the foliage of eight woody plant species: water oak ( Quercus nigra L.), live oak ( Quercus virginiana Mill.), red maple...

BACKGROUND Several previous epidemiological studies have shown a relation between drinking water quality and death in cardiovascular disease whereas others have not found such a relationship. An intervention study was undertaken to evaluate the effect of water with added magnesium and natural mineral water on blood pressure. METHODS A group of 70 subjects with borderline hypertension was recr...

Food flavour is important in appetite control. The effects of aroma and taste, independently or in combination, on appetite sensation and subsequent food intake, were studied. Twenty-six females (24 ± 4 years, 20.9 ± 1.9 kg,m 2) consumed, over 15 min period, one of four sample drinks as a preload, followed by an ad libitum consumption of a pasta meal (after 65 min). Sample drinks were: water (S...

this study was conducted to evaluate the water-use efficiency of rice (khazar cultivar) at rasht research institute of rice. the treatments were four different irrigation intervals (two, five, eight and 11 days) in a randomized complete block design (rcbd) with three replications. the plot size was 15 square meters in area and 50 cm in depth. the spacing between plants was 25 x 25 cm and the so...
